In medicine permanent magnets demonstrate unique advantages in terms of field strength, tunability of field and gradient distributions, and practical implementation. The findings highlight the critical role of spatial magnetic field characteristics in optimizing the interaction of magnetic fields with biological tissues and cells, thereby improving the efficacy of magnetic medical technologies. The insights derived from this study emphasize the transformative potential of permanent magnet systems in shaping the future of both magnetic surgery and therapeutic applications in medicine.

Bethesda, MD (July 29, 2025) — A new international study confirmed a significant post-pandemic rise in disorders of gut-brain interaction, including irritable bowel syndrome (IBS) and functional dyspepsia, according to the paper published in Clinical Gastroenterology and Hepatology.

A researcher at Osaka Metropolitan University investigated the active travel effects of an mHealth app that incentivizes daily walking. The results revealed that the mHealth app’s incentives to exchange train tickets increased users’ daily walking steps by 626.2 steps/day for five months.

Miniaturization and weight reduction of medical wearable devices for continuous health monitoring such as heart rate, blood oxygen saturation, and sweat component analysis remain major challenges. In particular, optical sensors consume a significant amount of power for LED operation and wireless transmission, requiring heavy and bulky batteries. To overcome these limitations, KAIST researchers have developed a next-generation wearable platform that enables 24-hour continuous measurement by using ambient light as an energy source and optimizing power management according to the power environment.

Researchers from The University of Osaka have used a miniature heater positioned over a nano-sized opening to gently unzip DNA’s double helix into a single strand for quick, efficient analysis. The device enables detection of longer DNA strands than before while using less power and improving accuracy. The technology could be used in handheld medical devices, helping doctors to diagnose disease and tailor treatments based on patients’ genes.
